The chief types of sea coasts are (i) steep rocky cliffs, (ii) broad low beaches, (iii) small bays alternating with rocky headlands, and (iv) sandy tidal flats. Shorelines: A “shoreline” is the line along which the water meets the land. Shorelines are classified into three groups: (i) […]

A glacier is a thick mass of ice, which moves over the ground under the influence of gravity. It originates on land from the compaction and recrystallization of snow. Glaciers form in places where more snow accumulates each year than that melts away. They are found chiefly in high attitudes as in the Arctic regions, or at high elevations as on the Himalayan mountains above the snow-line. The snow line […]

To understand the concept of the cycle of landscape evolution, let us start with a relatively flat upland area in a humid region. During the youth stage, the area remains more or less flat. The stream valleys are generally narrow. In the mature stage, the land’s relief increases, and the landscape changes into one consisting of hills and valleys. The “relief” of an area may be defined as the maximum […]

A large portion of the rainwater is absorbed by the earth’s surface. Streams are created when excess water from rain, snowmelt, or near-surface groundwater accumulates on the ground surface and begins to run downhill. This excess water from rain or snowmelt generally occurs when the water accumulates at a faster rate than the soil and organic matter can absorb the water, plants can use it, or the water can be […]
